To all 'whom it may concern:

.Be' it known that I, EDWARD J. Roma? 'BAGHER, a citizen of theUnited States, residing at Blaine, in the county of WhMDCOIIL and State of Washin ton,- have invented a new-and useful Hose onnection for Wheellires, &c., of which the following is a specifioation.

This invention hasreference to-improvements in hose connections for wheel tires for automobiles or bicycles or for any other purpose where'air is to be used, and the object of the invention is to provide a hose connection which can be used either as an 'automatic or as a positive connection.

The invention is designed for the coupling ofa source of-air supply under pressure to pneumatic tires or other receptacles for compressed air which will permit of the passage of compressed air only after the coupling or connection has been screwed properly to the part through which the air is to be forced.

The improved coupling comprises avalve structure which automatically closes onthe air pressure side to the passage of compressed air from the reservoir or compressor to the part into which the compressed air is to flow until the coupling has been firmly connected to the tire or to any other receptacle into which the air is. to be delivered.

The invention not only comprises an auto- I matic connection but includes means whereby the valve in the connection may be held positively closed until the connector is coupled to the receptacle into which the compressed air is to-flow, after which the intermediate valve may be released.

The invention will be best understood by a consideration of the following detail de seription taken in connection with the accompanying drawings forming part of this specification, inwhich drawings Figure l is a. central longitudinal section of'the improved hose connection, with parts shown in elevation. Fig. 2 is a cross section on the line a2:c of Fig. 1. Fig.3 is a detail View of an adapter which maybe used in connection with the structure of Fi 1 and 3. Fig. 4 is a longitudinal .centra' section through a hose connection constructed in accordance with the invention, but differing in some particulars from the showing of Fig.- 1. 1 Figs, and 6 are detail views of other forms of adapters than that shown in Fig. 3.

Consider ng the hose connector as being used upon a pneumatic tire for tin-automotaken as indicat ve onl to size or proportions, w ich may be changed a may be necessary to adapt the structure-- bile or bicycle wheel, the showi in the drawing is exaggerated in size, but or other purposes the showing of the drawing-is more nearly correct. It is to. be understood that the size of the structure will depend entirely upon the use to. which it is app ied. A There, fore the showi, of the drawing is to be without reference to various uses to which it may be applied.

Referring to the drawings, there is show-u in Fig. 1' a cylindrical block-'1. formed at its lower end with a laterally exten ing Q11- nu ar flange 2. The upper portion of the main body o-fthe block is frustq-cbmca}, as indicated at 3., and finally terminates, ma cylindrical neck 4, threaded at the where it joins the frusto-cgnical section of the blflck, as indicated at 5, and also at-the free of the sleeve, as indlcoted at 6. There is formed in the nterio of he sleeve 4. a e lindijical chamber 1 extendingto a point :2. out midway of the length of the frustorconi al portion 3. where there 15 formed anmwa dlyirected taperffaced annular flange 8 constituting a valve seat and below this PDlftion the interior chem r is of less diamete as indicated at 9. The chamber 9 extends to and opens at the flange end of the block 1. Surrounding the main cylindrical portion of the block 1 is a cup. 10. havin its 10 is screw-threaded'as. indicat d at 13, to

receive a bushing- 14 having the end exterior to the-cup 10 expanded to the diameterf the cup, as Indicated at. 15, and thispm'nqn 15, is provided with radial outwardlysgqtendingknobs 16 slmilar to. the contour of an ord nary valve wheel handle. Above the neck- 11 thecup 10 is formed with an annular recess 17 opening into the larger portion 0 of the cup.

Within'the chamber .9 there is' l'maed a' h llo y indr cal stem 1.8 rou ded or larly shaped at one end and there provided with th fih passages 1 below the apex o the noun 0 end- Theother end of h cylinder 1811s. fre ly op ned and 1s ormed with an ester arannular red a ange 2.01 Surrounding he e hnder 1 n h cone- .spondi-n side oft e flange is a washer 21 and ent we other side of the flan e is ano her washer 22. The washers 21 a 22am be made of leather or other suitable material and maybe fastened to the flange in any Suitable manner. Within the neck 4 there is contained a cylindrical block 23 on one side of which pro ects a valve stem 24 terminat ing in a conical valve head 25 ada ted to the seat 8. Extending from the'en of the block 23- remote vfrom the valve stem 24 is another stem 26 forming a guiding member for one end of a helical spring 27'housed in the neck 4 and engaging at the end remote from the block 23 against a cap 28 screwed onto the threaded end 6 of theneck 4. The

cap 28 has a central perforated assage for the threa'ded end 29 of a .thum screw 30 arranged axially to the stem 26. The cap 28 is-formed with an annular neck 31 exteriorly threaded for the reception of a packing nut 32 confining suita 1e packing 33 around the threaded 'end '29 of the thumb screw within the neck 31.

The chamber 7 about midway. of the length of the frusto-conical ortion 3 of the block 1 is formed with a si e port 34, and coincident to this port the frusto-conical portion 3 has an exterior annular groove 35.

itted tothe frusto-conical portion 3 of the block 1 is a collar 36 having its internal bore adapted to snu ly fitthe conical surface of the section 3 0% the block '1. This collar is 'formed-with a port 37 leading-into a nipple -38 shaped to receive the end of a piece of hose or other flexible conductor. The collar 36iis held in place about the frusto-oonical section- 3 by a nut 39. adapted to the threaded portion 5 of the 'neck 4, and the construction is such that with properly ground joints be-' tween the -frusto-comc'al portion 3 and the interior of the collar 36 the connection between the collar 36 and thepart car g the same may be made and inaintaine tight, the nut 39 being so arranged as to take up wear. 4 The threaded neck 11 is adapted to be screwed onto thethreaded nipple of a neu Y matic tire or other structure into whic of different sizes.- Between. the two parts 40 and 41 the coupling is provided' with a polygonal flange 43 by means of which the sai coupling may be screwed into the part to'which it is'adapted. I 2

Let it be assumed thatth e mhpple 3,8.has applied thereto the end ofaf ex'ible hose "coming from a supply of air under pressure.

Under these conditlons the air ressufe will tend to firmly seat the valve 25 mthe seat 8,

this valve being normally seated bythe ac tion of-the spring 27.- The valve head25 is of conical shape with itsapex slightly flatgagement with said block. 1

an axial passa tened and normally enga g the rounded end of the cylinder or sten 1 i8. Air is thus prevented from passing from the nipple 38 to the neck 11, it being understood that the v valve seat 8 and valve head 25 are pro erly fitted to prevent the normal passageoi air. If, now, the neck 11 be screwed onto a suitable ni ple, say that on the free end of the stem 0 a pneumatic tire, this nipple will extend into and through the neck 11 and its free end will engage the washer 22 and force the stem 18 against the valve head 25 and move the latter against the action of the spring 27 until the washer 21 is finally in engagement with the flanged end of the block 1 with the free end of the nipple of the tire valve in firm engagement with the washer 22 and force the stem 18 against the valve head 25 and" move the latter against the action of the spring 27 until the washer 21 is finally in engagement with the flanged end of the block 1 with the free end of the nipple of the tire in firm enga ement .with the washer 22. Air will now ow throu h the port 34 and by the valve 25 into t e chamber 9, and thence through the openings 19 into the interior of the, stem 18 and ultimately into the tire or other receptacle. The two washers 21 and 22 form air tight o ints between the corresponding end of the block 1 and the nipple end of the valve stem of the tire so that no packing is required other than these two washers 21 and 22.

of the projections 16 by means of which the cup 10 is easily rotated upon the block 1, this cup being normally in quite loose encapable of The hose-receiving nipple 38 is being rotated with the collar 36 entirely around the end 3 of the block- 1' and the groove 35 admits air to the port 34 irrespec tive of whether the port 37 of. the nipple 38 is in line with the port 34 or not.

on its outer surface. with annular grooves 45 for the reception of a hose. The free end of the neck 44 is tapped to receive the thread ed end of a plug-46 throughtwhich extends ,47. The block. 46 serves to confine a he lcal'spring 48within theinterior of the neck 44, and this sprin engages a ball 49 normally seated on the va ve seat 8 which in this instance is properly shaped to receive the M1149. The stem 18 of the movable into e sure' is to be introduced. I

sam

structure of Fig. 4 is like the stem 18 of the structure of Fig. 1, except thatits free end, ement with the ball valve, may be slight y modified in shape to adapt it to en the ball valve, or this item may be t e same shape as shown in In Figs. 5.and 6 arefshown other forms of adapters which may be used in connection with the structures of either Figs. 1 or 4.

'In Fig. 5 there is shown an adapter 49 having one end 50 threaded to enter the neck 11,- while the other end 51 is threaded .to enter a threaded socket or coupling of an ordi- 'pise, the said end 51being provided wit or inary pipe threads of suitable size. In the structure shown in Fig. 6 there is illustrated an adapter 52 having a nipple 53 threaded to enter the neck 11 and a hosereceiving neck 54 on the end opposite the nipple .53 to receive an ordinary hose. The adapter ofFig. 5 is for j urpose of connecting up the structures 0 either Figs'l or 4 to an iron pipe conduit while the adapter of Fig. 6 is desi ed to connect u the structures of either igs. 1 or 4 wit a hose conduit. i. g

' The structure of Fig. 4 is of the automatic type only and .the positive connection shown inFig. 1 is omitted. While the application of this invention has been limited more particularly to pneumatic" tires, it is to be understood that it may be applied to -fire sprinkling systems and other purposes where its action may be utilized and the parts will be made large or small and heavy or light in accordance with the particular conditlons under which the device is to be used.
